It will be readily understood by those skilled in the art that by theuse of my improved support a large number of Wires can be readily placedin position and the drawing of the Wire through each support is entirelyavoided.

I claim herein as my invention 1.

2. I11 a carrier for signal-Wires, the combination of a frame, one ormore posts or plates intermediate of and shorter than the sides, two ormore pulleys or rollers loosely mounted between the intermediate postsor plates and the sides, a second frame adapted to fit between the sidesof the first frame, two or more rollers mounted in the second frame, andmeans for removably securing the second frame in position, substantiallyas set forth.

3. In a carrier for signal-wires, the combination of a U-shaped oropen-topped frame, one or more posts or plates intermediate of the sidesof the frame, one or more rollers loosely mounted in the slots orpockets formed by the posts or plates and sides of the frame, and adetachable crossbar for holding the wires in the slots or pockets,substantiallyas set forth.

In testimony whereof I have hereunto set my hand.
